The answer, using an indicator to measure the hydrogen ion concentration of a solution, is correct
Carbon, hydrogen, nitrogen and oxygen are all non metals.
4. KE increases by a factor of 16 is the answer
<u>Explanation:</u>
Kinetic energy = (1/2)mv² = 0.5 mv²
where
m = mass, and v = velocity.
So at 15 mph,
K
E = 0.5 m (15)
² = 112.5 m
And at 60 mph,
K
E = 0.5 m (60)² = 1800 m
m is the mass, and not meters.
So, 1800 m/112. 5 m = 16
16 times the Kinetic Energy.
Answer:What is the acceleration of a car that moves from rest to 15.0 m/s in 10.0 s? Vi=0, vf= 15.0 m/s,t=10.0s, a=? a= vf =vi/tA=15.0m/s-0m/s/10.0s = 15.0s/10.0s m/s*1/s =1.50 m/s^2 11.
Explanation:
The point with the greatest potential energy is B.
The potential energy of an object is depends on the relative distance between the object and the ground and its mass. The higher the object is from the ground the greater the potential energy posses.
Potential energy (P.E) = mgh
Where m is the mass, g is the gravity and h is the height from the ground to where the object is.
Since the mass and gravity is constant in this case, only the height will determine the point with the greatest P.E and that point is B.
